Langen/Germany and Yokohama/Japan, 21. December, 2023 --- Socionext Inc. today announced that its paper entitled “Consideration based on ESD applied waveform in High-Speed IF using T-Coil” was highly acclaimed and recognized with the Friendship Award when presented at the 45th Annual EOS/ESD Symposium & Exhibits held at the Riverside Convention Center (California, USA) between September 30 and October 5, 2023.
Achieving high levels of quality and reliability is an important requirement when developing large System-on-Chip (SoC) devices for automotive, data center, and networking applications with increasingly advanced in functionality and performance.
Accordingly, when developing the high-speed interfaces (PCI Express and USB, etc.) used for input and output on SoCs, it is essential that they are designed for high robustness to electro-static discharge (ESD) as well as high-speed.
Socionext has made progress on the extremely important objective of improving ESD design accuracy by developing an ESD design technique that utilizes high-frequency circuit simulation and by using test chip measurements to evaluate its suitability.
The paper reported some of the outcomes of this technology development, contributing to improvements in SoC reliability by first identifying the pitfalls in existing ESD design techniques, then elucidating their mechanisms and specifying the ESD design policies to be used henceforth.
Summary of paper
Title: Consideration based on ESD applied waveform in High-Speed IF using T-Coil
Synopsis: While the T-Coil circuit can reduce the effect of parasitic capacitance of the ESD protection circuits, instances have been reported of internal circuit damage resulting from mutual induced voltage. In this paper the study conducted using a test chip fabricated by cutting-edge CMOS technology discovered that the very fast transmission line pulse (VF-TLP) measurements widely used for ESD design deliver more pessimistic results than the charged device model (CDM) measurements used for compliance testing, and determined the reasons for this.
Care is needed when performing ESD design as T-Coil circuits are a new instance of where TLP measurement and ESD measurement do not give the same results.
